Given the wide range of air pollutants and their sources and the large number of impacts that these have, it is important that comprehensive and sophisticated systems of regulation and management are adopted. Over time, these systems have indeed developed, and this chapter will describe them. Initially it provides an examination of regulation in the UK. This includes the system of Integrated Pollution Control, which also controls emissions to freshwaters and the seas. The international context (EU and UN) is also extremely important, as air pollution is often trans-boundary. Management of air pollution requires a range of monitoring and modelling techniques, and these are described. Finally, the wide range of management options for control of air pollutants in three areas: industry, agriculture and traffic, are discussed.
